Geoportal Server is a standards-based, open source product that enables discovery and use of geospatial resources including data and services. Geoportal Server allows you to catalog the locations and descriptions of your organization's geospatial resources in a central repository called a geoportal, which you can publish to the Internet or your intranet. Visitors to the geoportal can search and access these resources to use with their projects. If you grant them permission, visitors can also register geospatial resources with the geoportal. Geoportals give you an enterprise-level view of your geospatial resources regardless of their type or location. Resources are registered with a geoportal using metadata, which describes the location, age, quality, and other characteristics of the resources. With access to this information about resources, an organization can make decisions based on the best resources available. Geoportal Server has been hosted on SourceForge since 2010. We are in the process of migrating to GitHub as part of Esri's larger effort to support developers of the Esri platform with open source apps, samples, and SDK. Stay tuned for updates of this migration process.
